HIRAM CARPENTER, OF NEW YORK, N. Y.

IMPROVED RAILWAY-CHAIR.

Specification forming part of Letters Patent No. 59,180, dated October30, 1866.

To all whom t may concern:

Beit known that I, HIRAM CARPENTER, of New York, in the county and Stateof New York, have invented a certain new and useful Improvement inRailway-Chairs; and I do hereby declare that the following is a full,clear, and exact description ot the same, reference being had to theaccompanying drawings, making a part of this specification, and to theletters of reference marked thereon,

My invention relates to railway-chairs provided with india-rubber orother elastic seats for the rails, and holding the rail, or the ends ofthe adjacent rails, with a loose cheek or separate side piece, thatlocks into the body of the chair and is wedged by a small key.

To enable others skilled in the arts to which it appertains to make anduse my invention, I will proceed to describe its construction andoperation with reference to the drawings.

Figure l is a section of the said chair, and Fig. 2 is a plan of thesame.

rIhe rail t rests upon the india-rubber bh, which is'retained in arecess ofthe chair, that keeps it from spreading.

The rail is held and supported on one side by the cheek c, which is caston the main portion of the chair, and on the other by theloose cheek1,Which is cast separately, and is so made that it locks into the chairin the manner shown, and is secured by the key 7c, by which it is wedgedto hold the rail firmly in position.

If the india-rubber Were not confined in .a

recess, or some corresponding means adopted for its protection, it wouldin course of time be so much flattened or crushed out that it would beof little or no use, and by keying up the loose cheek and compressingthe india rubber the excessive range of elasticity is re. stricted tothe degree required to avert the concussion of a passing weight.

The base of the chair may be extended to afford a sufficient support onthe ballasting of the road-bed, or it may be bolted or spiked to iron orWooden cross-tics, in the ordinary manner.

As it may not always be necessary to clamp the rail at any other pointthan at the joints, the intermediate chairs may be made lighter inconstruction by omitting the loose cheeks. These intermediate chairs maybe so placed on curves that their stationary cheeks resist any tendencyto lateral displacement, and they may be placed on a straight section ofthe road with the cheeks of the adjacent cha-irs sustaining oppositesides ofthe rail.

I claim- The railway-chair constructed with an clastic support, combinedWith a loose jaw that locks into the body of the chair and is tightenedby a key, substantially as described.

HIRAM CARPENTER.
